A study on motility of spermatozoa of the Persian sturgeon, Acipenser persicus were carried out. The time of relative cessation of sperm activity was evaluated using microscopic observation. Sperm was activated with three different swimming medium, freshwater pH 7.5, and two different buffered saline solutions, pH 7.5. Total period of the motility of A. persicus spermatozoa was shorter in fresh...

Some haematological variables including Red Blood Cells (RBC), White Blood Cells (WBC) differential counts, Haemoglobin (Hb), Haematorite (HCT), Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH) and Mean Corpuscular Haemoglobin Concentration (MCHC) were measured in 90 stellate sturgeon juveniles Acipenser stellatus (1-2 years old) and 90 Persian sturgeons Acipenser persicus (1-2...

Persian sturgeon, Acipenser persicus is a native, commercially important and highly steemed fish species in the Caspian Sea. In this study, effects of Nodularin (NODLN), a cyclic pentapeptide hepatotoxin, on liver and gill tissues of A. persicus were studied. Nodularin was produced in high amounts by Nodularia spumigena, a cyanobacterium species during the algal bloom in the Caspian Sea an...

In this study, random sampling conducted and 90 individuals of Persian sturgeon having 3-5g weight, collected by trawling in 3 earthen ponds and 15 individuals having 10-20g weight, collected by small net in 3 fiberglass Vans. After recording of biometrical characteristics, the intestine and rearing water were cultured on TSA medium. Gram staining and complementary tests were conducted. In orde...

Objective- Acipenser persicus is one of the most important caviar producing fishes in the Caspian Sea and one of the endangered species of the sturgeon fishes. For breeding of sturgeons, large numbers of animals have to be captured and examined to obtain sufficient numbers of mature fishes that will spawn within a few months in captivity. Design- Original study Animals- A total of 66 adult Acip...
